Time-reversal symmetry-breaking superconductivity in heavy-fermion PrOs4Sb12 detected by muon-spin relaxation.
We report on muon-spin relaxation measurements of the 4f(2)-based heavy-fermion superconductor filled-skutterudite Pr(Os4Sb12. The results reveal the spontaneous appearance of static internal magnetic fields below the superconducting transition temperature, providing unambiguous evidence for the breaking of time-reversal symmetry in the superconducting state. A discussion is made on which of th...
متن کاملA New Heavy Fermion Superconductor: the Filled Skutterudite Compound Pros 4 Sb 12 *
The filled skutterudite compound PrOs4Sb12 exhibits superconductivity below a critical temperature Tc = 1.85 K that develops out of a nonmagnetic heavy Fermi liquid with an effective mass m∗ ≈ 50 me, where me is the free electron mass. Analysis of magnetic susceptibility, specific heat, electrical resistivity and inelastic neutron scattering measurements within the context of a cubic crystallin...
متن کاملSuperconductivity in the platinum germanides MPt4Ge12 (M = rare-earth or alkaline-earth metal) with filled skutterudite structure.
New germanium-platinum compounds with the filled-skutterudite crystal structure were synthesized. The crystal structure and composition were investigated by x-ray diffraction and microprobe analysis. Magnetic susceptibility, specific heat, and electrical resistivity measurements evidence superconductivity in LaPt4Ge12 and PrPt4Ge12 below 8.3 K. The parameters of the normal and superconducting s...
متن کاملHeavy fermion superconductivity in the filled skutterudite compoundPrOs4Sb12
The filled skutterudite compound PrOs4Sb12 has been found to exhibit superconductivity with a critical temperature Tc = 1.85 K that develops out of a heavy Fermi liquid with an effective mass m ∗ ≈ 50 me. The current experimental situation regarding the heavy fermion state, the superconducting state, and a high field, low temperature phase that is apparently associated with magnetic or quadrupo...
متن کاملDefect-enhanced void filling and novel filled phases of open-structure skutterudites.
We report the design of novel filled CoSb3 skutterudite phases based on a combination of filling and Sb-substituted Ga/In defects. Ga/In doped skutterudite phases with Li-, Nd-, and Sm-fillings can be formed via this strategy, which can have relatively wider ranges of carrier concentration than other conventional filled skutterudite phases.
